Specification of Letters Patent.

Patented April '7, 1908.

Application `tiled November 9, 1907. Serial No. 401,409.

T o all whom 'iff/nay concern: Beit known that i, FRANK R. BIGLER, a

`citizen of the United States, residing at Kansas City, inthe ,county ofJackson and State of Missouri, have invented certain new and useful lmrovements inHeat-Deflectors; and I do dec are the following to be`afull, clear, and exact description ofthe invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part ofthis specification.

My invention relates to heat deectors, and more particularly to a deviceof that class for use in stoves and furnaces adapted for yburning fuelgas; the object of my invention being to provide a deiiector with whicha substantially perfect combustion may be secured, and by which the heatfrom the burning fuel is so directed as to secure the greatesteiiiciency therefrom.

A further object is to provide the improved details of structure which iwill presently describe and claim, the same being illustrated in theaccompanying drawings, in

Referring more in detail to the parts 1 designates the fire pot and 2the outer casing of an ordinary hot air furnace; the former beingprovided with the customary flue 3 and heat coil openings 4, and thelatter being provided with the air pipes 5, which lead to the apartmentsto be heated.

in the fire pot l is the grate-6, and in the casing, below the grate, isthe ash door' 7.

Entering the furnace; through casing 2 or door 7, as may be desired, isthe fuel supply pipe 8, which extends upwardly through ygrate 6 and isconnected with the perforated burner coils9by a Y union 10 said coilsbeing suitably supported in the i'ire pot and preferably comprisingrings of dierent diameter, set 'one above the other.

. Supported on grate 6 is a heat deiiector,

preferably made up of individual pieces 11, having narrow, curved baseportions 12, vadapted to seat in a circle near the center of the grate,and having the flaring end portions' 13, which extend over the burnercoils 9 to the inner surface of the fire pot, with which they contact;the outer end of each piece 11 being provided with a recess 14, throughwhich the smoke and fumes from the burners may rise.

ln assembling the arts, the burner coils are set in substantial y theposition shown, these coils being preferably two in number and formed incircles, although the number of coils may be varied to meet dierentrequirements, and the contour of 4the burners varied according to thestyle of the furnace. After beingset, the coils are connected with thesupply pipe by any suitable union, the Y construction shown beingpreferable where one coil is set above and to one side of the other.

`When the burners have been installed, the deliector is set in placethereover, so that the heat rising from the burners, when the furnace isin operation, will rise against its under surface and be conducted uwardly and outwardly, to contact with the fire pot, from which the heatis radiated to the chamber between the fire pot and casing, and fromthence is conducted through pipes 5 to the apartments.

By having a covering over the burners, the air coming in throug/htheburners and grate openings is carried upwardly to the periphery of 4thedeflector, andl then passes upwardly through the deflector recesses 14to the top of the fire pot, where the smoke and fumes pass out throughthe flue.

By placin one of the burner'coils slightly over the ot er, .the heat,rising from the lower coil, will heat the upper, and the gas from theupper coil is delivered in a highly combustible condition; and byinclosing the coils, the fuel particles are spread when they contactwith the deflector and a'substantially perfect combustion secured.

Vhile l have described the deflector as being formed in sections, it maybe in a single piece, if desired, with the'recesses 14 cut from its perihery; the sectionalconstruction being re erable however, owing to thegreater fac` ity with which it may be installed; and while l prefer toconstruct the deflector of iire clay, it may be of cast or sheet metal,if desired.

While I have described my s to the deflector described, which may beused in combination with any stove or furnace, and particularly to thoseadapted for burnin fuel gas.

aving thus described m invention, what I claim as new therein and esireto secure by Letters Patent is 1. A de'lector unit comprising a bodymember that is narrow at one end and flares toward the other end, theflared end of said member being provided with a recess and the narrowend wlth a curved leg portion, subo stantially as and for the purposeset forth.

2. The combination with a suitable lire pot, and a defiector located insaid fire pot over said burner, said deiiector comprising individualunits having flared outer ends resting against the iire pot and narrowinner ends terminating in downwardly curved le s which support saidunits at the center of sald grate, the iared ends of said units beingrecessed, substantially as and for the purpose set forth. y

In testimony whereof I alix my signature in presence of two witnesses.FRANK R. BIGLER. Witnesses:
